“板块论”和“相对论”、“量子论”一样被人们称为20世纪最重要、影响最大的科学理论之一。“板块”是加拿大人威尔逊在1965年提出的,他认为连绵不断的活动带网络将地壳划分为若干刚性块体,它厚度大约为10～60千米,但相对6371千米的地球半径来说,只能算是薄板了,所以把它称为板块。板块论自20世纪60年代末被提出后,很快风行世界。它是在魏格纳的“大陆漂移 “Plate theory” is also called “the theory of relativity” and “quantum theory” as one of the most important and most influential scientific theories of the 20th century. “Plate” was proposed by Canadian Wilson in 1965. He believes that the continuous activity belt network divides the earth crust into several rigid blocks. Its thickness is about 10 to 60 kilometers, but it is relative to the earth radius of 6371 kilometers. It can only be considered a thin plate, so it is called a plate. The plate theory has been popular since the late 1960s. It is in Wigner’s "continental drift
